Abstract

The knee is the joint that most frequently results in impaired function and incapacity in the elderly. While unmistakable treatment by prosthetic substitution is many times performed late, suggestive knee ligament sores cause a lot enduring likewise in more youthful ages. As a result, early intervention could be implemented to the benefit of patients and society at large. Implants for resurfacing with a small metal surface have been tried, and the results look promising. A system with patient-specific implants and surgical instruments has favourable survival rates and good clinical results. The purpose of this study is to compare this metal device to microfracture (MFX), which is the standard procedure in Sweden, in terms of cost-to-benefit.
